The 49ers promoted cornerback Asa Jackson from their practice squad and waived fellow corner Keith Reaser to clear a roster spot, Matt Maiocco of CSNBayArea.com tweets. A fifth-round 49ers pick in 2014, Reaser played in 29 games for the team — including last week’s loss to the Panthers — but didn’t start any. San Francisco signed Jackson, an ex-Ravens starter, in August and stashed him on the practice squad after the preseason.

Nose tackles Kyle Peko and Tyrique Jarrett will once again trade places with the Broncos. Denver will promote Peko from its practice squad and waive Jarrett, Nicki Jhabvala of the Denver Post tweets. A rookie UDFA out of Pittsburgh, Jarrett saw Week 1 work on a depleted Broncos line. Peko, a cousin of Broncos starting nose Domata Peko, was waived last weekend.

The Colts promoted linebacker Darnell Sankey from their practice squad, cutting wide receiver Matt Hazel to make room, Mike Chappell of IndySportsCentral.com reports (via Twitter). Both Antonio Morrison and Anthony Walker are dealing with injuries, making this an insurance addition.
